NOAA OWP NextGeneraton Modeling Framework Hydrofabric

What is it?

Nextgen hydrofabric artifacts are distributed by NHDPlusV2 Vector Processing Units. They are generated from a set of national reference datasets cite built in collaboration between the USGS and NOAA. These artifacts are designed to be easily updated, manipulated, and quality controlled to meet the needs of a wide range of modeling tasks.

How do I get it?

Nextgen artifacts are publicly available through a partnership with Lynker and the NOAA OWP by VPU. For each VPU two artifacts are available

a geopackage that contains all tables, spatial data, and lookups relvant to a hydrofabric logical model
a zip folder containing the files needed to run the Next Generation (Nextgen) Water Modelling Framework.

These can be programatically accessed using the respective URL patterns:
